- server for changing NIS information

Synopsis

/usr/lib/netsvc/yp/rpc.ypupdated [-is]

Description

ypupdated is a daemon that updates information in the Network Information Service
(NIS). ypupdated consults the updaters(4) file in the /var/yp directory
to determine which NIS maps should be updated and how to change
them.

By default, the daemon requires the most secure method of authentication available
to it, either DES (secure) or UNIX (insecure).

On start up, ypupdated checks for the existence of a NIS to
LDAP (N2L) configuration file, /var/yp/NISLDAPmapping. If the file is present, ypupdated generates
an informational message and exits. ypupdated is not supported in N2L mode.

Options

-i

Accept RPC calls with the insecure AUTH_UNIX credentials. This allows programmatic updating of the NIS maps in all networks.

-s

Accept only calls authenticated using the secure RPC mechanism (AUTH_DES authentication). This disables programmatic updating of the NIS maps unless the network supports these calls.

The Network Information Service (NIS) was formerly known as Sun Yellow Pages
(YP). The functionality of the two services remains the same. Only
the name has changed. The name Yellow Pages is a registered trademark
